§ Deep dives
The hard parts
Airspace, charts, weather decoding, and the physics. Each lesson is built around one thing you can drag, tap, or set, because these are spatial ideas and reading about them only goes so far.
- Airspace, from the ground upDrag a drone through a side view of the sky beside an airport and watch the class, the floor and ceiling, and the authorization rule change under it.
- Reading a sectionalReal chart excerpts from the FAA test supplement you can pan, zoom, and tap. Every symbol explains itself, and a find-it mode asks you to locate things by name.
- The chart's airspace ringsThe same chart excerpts with airspace classes toggled on one layer at a time, each ring's floor and ceiling explained where it is drawn.
- Latitude and longitudeEnter a coordinate and watch the chart point light up, or tap the chart and read the coordinate off; then find airports by coordinate the way the test asks.
- Decoding METAR and TAFA real-format METAR lights up one token at a time with its plain meaning; then decode a fresh one and get checked, and read a TAF's change groups.
- Cloud clearanceDrag a drone around a cloud and watch the 500-below, 2,000-beside envelope turn legal and illegal, with the visibility rule alongside.
- Density altitudeThree sliders, one answer: how field elevation, pressure, and temperature combine into the altitude the air thinks it is at, and what that does to a small aircraft.
- Weight, balance, and CGSlide a payload along a drone and watch the centre of gravity move against its limits, then see what a banked turn does to the load.
- The traffic pattern and runwaysSet the wind, watch the active runway and the pattern legs recompute, and hear what a pilot on each leg would say on the radio.
- Right-of-way and see-and-avoidSix short encounters with manned aircraft, each with three choices. The right one is always the same shape, which is the point.
- Civil twilight and nightA 24-hour dial for any date and place that shows day, the two 30-minute civil twilight windows, and night, with what each demands of you.
